A plane electromagnetic wave of wave intensity `6 W//m^(2)` strikes a small mirror of area `9 cm^(2)`, held perpendicular to the approaching wave. The momentum transferred in kg-ms by the wave to the mirror each second will be:

`1.2xx10^(-10)`

`2.4xx10^(-9)`

`3.6xx10^(-8)`

`4.8xx10^(-7)`

Text Solution

Verified by Experts

The correct Answer is:

Transferred momentum/secound to mirror is
`P=(2AS)/(c)=1.21xx10_(10) kg ms ^(1)`
